C# Program To Demonstrate The Use Of Failfast() Method Of Environment Class

The environment class provides information about the current platform and its customizations. It helps you get and set various operating system-related information. It gives you access to information such as command line arguments, exit codes, environment variable settings, call stack contents, and the time (in milliseconds) because of the last system startup. This procedure can be overloaded in two different ways:

1. FailFast(string message):

This method immediately terminates the process after emitting the Windows Application Event Log so that the message is included in the error report to Microsoft. It terminates the process without running any finalizers or try/catch blocks.

Syntax:

It has the following syntax:

public static void FailFast(string message)

Here, the message may be a message that will be logged within the Windows application event log , or it clarifies why the end happens. It can only be valid when clarification is given.

2. FailFast(string msg, Exception):

This method is utilized to end the method immediately after composing the Windows application event log and includes the message and exceptions within the blunder report to Microsoft. Here, the exemption does not handle since the method is ended but can get the data due to which exception happens. In this strategy, when the exemption is invalid at that point, the FailFast(string msg, Exception) method carries on like the FailFast(string message) strategy. Moreover, the method end without running the finalizers or try/catch square.

Syntax:

It has the following syntax:

public static void FailFast(string message, Exception)

Example:

FileName: FailFastSample1.cs

// Program to implement the use of FailFast() method in C#
using System; 
class FailFastSample1{ 
static public void Main() 
{ 
	
	//The statement that displays the code before the termination
	Console.WriteLine("The code Before termination"); 
	
	// Using the FailFast() method for the code termination
	Environment.FailFast("Terminate the program"); 
	
	// The code after the termination
	Console.WriteLine("The code after the termination"); 
} 
}

Output:

The code Before termination
CLR: Managed code called FailFast, saying "Terminate the program"

=================================================================
	Native Crash Reporting
=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Example 2:

In this example, we can use the mathematical operations before the code termination.

FileName: FailFastSample2.cs

//  Program to implement the use of FailFast() method in C#

using System; 
class FailFastSample1{ 
	
static public void Main() 
{ 
	
	// the mathematical operation for adding two numbers
	int s = 30 + 20; 
	Console.WriteLine("The Sum is: " + s); 
	
	// The statement that displays the code before the termination

	Console.WriteLine("The code before termination"); 
	
	//Using the FailFast() method for the code terminatio
	Environment.FailFast("Terminate the program"); 
	
	//  The code after the termination

	Console.WriteLine("The code after the termination"); 
	
	//  the mathematical operation for subtracting two numbers
	int diff = 30-10; 
	Console.WriteLine("Subtraction Value: " + diff); 
} 
}

Output:

The Sum is: 50
The code before termination
CLR: Managed code called FailFast, saying "Terminate the program."

	Native Crash Reporting
============================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

Advantages of FailFast Method of Environment Class:

There are several advantages of FailFast Method of Environment Class. Some main advantages of the FailFast Method of Environment Class are as follows:

• ✅ Generate Crash Dumps:

When the FailFast method is called, it generates a crash dump of the application's procedure. This crash dump carries valuable facts about the country of the utility at the time of the failure. Crash dumps may be analyzed with the use of debugging tools to discover the root reason for the failure, which makes it less difficult to diagnose and fix critical troubles.

• ✅ Immediate Termination:

FailFast terminates the utility without delay and without permitting any further code execution. It is beneficial in conditions where continuing the execution of this system may result in unpredictable behavior or fact corruption. Immediate termination can assist in preventing similar harm and capability security risks.

• ✅ Critical Error Handling:

FailFast is typically used in scenarios wherein the utility encounters essential mistakes or unhandled exceptions that make it risky to keep running. It manages address such conditions and ensures that the utility exits in a recognized nation, which allows for correct cleanup or recovery procedures.

• ✅ Logging and Notification:

Before calling FailFast , you may log relevant data about the error, such as exception info and a custom error message. These logged records may be beneficial for autopsy evaluation and can also be used to notify directors or builders about important problems in the application.
